What is the definition of voltage in electrical systems?

• A. Voltage is current per unit length
• B. Voltage is the potential difference between two points
• C. Voltage is energy per unit time
• D. Voltage is the measure of electrical resistance

Answer: (B)

Voltage is defined as the potential difference between two points in an electrical circuit. It represents the work done per unit charge to move a charge from one point to another, thereby creating the necessary force that drives the flow of electric current through a circuit. This potential difference is fundamental in understanding how electrical systems work, as it determines the energy available to push electrons through conductors, enabling devices to function. The concept of voltage is crucial for anyone working with electrical systems, as it directly relates to how components such as resistors, capacitors, and inductors interact within a circuit. Understanding voltage helps in troubleshooting, designing circuits, and ensuring the safe operation of electrical equipment in aviation maintenance.
